Problems solved by technology

[0015] It can be seen from the above solutions that in the 3GPP-WLAN interworking network, there is already a relatively complete process for user terminals to select access networks. However, when a WLAN access network is connected to multiple VPLMN networks at the same time, and a user After the terminal has connected to one of the VPLMN networks through the WLAN access network, the user terminal needs to disconnect the currently connected VPLMN network for various reasons, such as: tariff reasons, access to service range reasons, etc., and reselect the WLAN When the access network is connected to another VPLMN network, or when the current user terminal expects to access A service through VPLMN1 and access B service through VPLMN2 at the same time, no one has proposed a specific solution so far

Embodiment 1

[0101] In this embodiment, after the home network receives the authentication request from VPLMN2, it directly performs the authentication operation, and the authentication is successful; and, after the authentication is successful, the home network first sends an access permission message to VPLMN2, and then sends the VPLMN1 sends a disconnection message; correspondingly, the WLAN access network first receives an access permission message. In addition, in this embodiment, only the current user is allowed to access one connection at the same time. Then, in this embodiment, the process for the WLAN user terminal to reselect the mobile communication operator network includes the following steps:

[0102] Step 11: The current WLAN user terminal determines that it needs to access the VPLMN2, and confirms the domain name or identifier of the VPLMN2.

[0103] Step 12: The WLAN user terminal sends an access authentication request to the WLAN access network without affecting the exis...

Embodiment 2

[0114] In this embodiment, after the home network receives the authentication request from VPLMN2, it directly performs the authentication operation and the authentication is successful; after the authentication is successful, the home network simultaneously sends an access permission message to VPLMN2, and sends a disconnect message to VPLMN1. connection message; and, the WLAN access network first receives the access permission message. In this embodiment, only the current user is allowed to access one connection or the user indicates to switch from an existing connection to a new connection. Then, the process for the WLAN user terminal to reselect the mobile communication operator network in this embodiment is basically the same as that in the first embodiment, except that step 28 is different from step 18 in the first embodiment.

[0115] Steps 21-27: are exactly the same as all descriptions of steps 11-17 in the first embodiment.

[0116] Step 28: The home network sends a...

Embodiment 3

[0118] In this embodiment, after the home network receives the authentication request from VPLMN2, it directly performs the authentication operation and the authentication is successful; after the authentication is successful, the home network simultaneously sends an access permission message to VPLMN2, and sends a disconnect message to VPLMN1. connection message; and, the WLAN access network first receives the disconnection message. In this embodiment, only the current user is allowed to access one connection or the user indicates to switch from an existing connection to a new connection. Then, the process for the WLAN user terminal to reselect a mobile communication operator network in this embodiment is basically the same as that in Embodiment 1, except that Step 38 and Step 39 are different from Steps 18 and 19 in Embodiment 1.

[0119] Steps 31-37: are exactly the same as all descriptions of steps 11-17 in Embodiment 1.

[0120] Step 38: The home network sends an access ...

Abstract

The invention discloses an interactive method for re-selecting an operating network for a wireless local area network (WLAN) user terminal, the method comprises following steps that: a. when a WLAN user terminal which is accessed to an accessing communication operating network needs to re-select accessing another accessing communication operating network, an authentication request of the WLAN user terminal is transmitted to an attributive network of the WLAN user terminal by a WLAN accessing network re-selecting accessing the other accessing communication operating network; b. the attributive network of the WLAN user terminal performs an authentication operation on the authentication request of the re-selected accessing communication operating network of the WLAN user terminal after receiving the authentication request, and transmits an operation indication to the WLAN accessing network via the accessing communication operating network; c. the WLAN accessing network completes breaking and accessing operations between the WLAN user terminal and the corresponding accessing communication operating network according to the operation indication after receiving the operation indication. The method make the user terminal can re-select another accessing communication operating network when being accessed to an accessing communication operating network already.

Description

technical field [0001] The invention relates to an operation network selection access technology, in particular to an interactive method for a wireless local area network (WLAN) user terminal to reselect an operation network. Background technique [0002] As users have higher and higher requirements on wireless access rates, a wireless local area network (WLAN, Wireless Local Area Network) emerges at the historic moment, which can provide high-speed wireless data access within a small range. Wireless local area network includes a variety of different technologies. A technical standard that is widely used at present is IEEE802.11b, which uses the 2.4GHz frequency band, and the maximum data transmission rate can reach 11Mbps. IEEE802.11g and Bluetooth (Bluetooth) technology are also used in this frequency band. , Among them, the highest data transmission rate of 802.11g can reach 54Mbps. Other new technologies such as IEEE802.11a and ETSI BRAN Hiperlan2 both use the 5GHz freq...
